Inclusion criteria
. Subjects diagnosed with prostate cancer through preoperative transrectal prostate biopsy and pathological examination, who are scheduled to undergo radical prostatectomy with or without pelvic lymph node dissection;
. Subjects must provide informed consent prior to trial initiation, fully understand the trial content, procedures, and potential adverse reactions, be capable of effective communication with the investigator, and be able to complete the trial as per protocol requirements. They must voluntarily sign a written informed consent form;
. Adult male subjects aged 18 years or older (including the boundary value);
. Gleason score ≥7, or imaging studies (transrectal ultrasound \[TRUS\] and/or prostate magnetic resonance imaging \[MRI\] or CT or PSMA PET/CT) demonstrating disease staging ≥T2, or imaging evidence of regional lymph node enlargement suggestive of lymph node metastasis;
. No hepatic or renal impairment: Hepatic: Total bilirubin ≤ 2 times the upper limit of normal (ULN) (excluding Gilbert syndrome), alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤ 3×ULN; Renal: Creatinine clearance ≥ 50 mL/min/1.73 m² (simplified MDRD formula);
. The investigator determines the subject has no clear contraindications for surgery and is suitable for radical prostatectomy;
. The subject and their partner or spouse must agree to have no plans for pregnancy or sperm donation from the screening period until 3 months after trial completion, and voluntarily use effective contraception.
Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Evaluate the efficacy of DGPR-1008 (administered 12 hours prior) in conjunction with a near-infrared fluorescence imaging device for intraoperative detection in patients.
Timeframe: From the screening period to the Day 7 of the trial
2
Evaluate the efficacy of DGPR-1008 (administered 24 hours prior) in conjunction with a near-infrared fluorescence imaging device for intraoperative detection in patients.
Timeframe: From the screening period to the Day 7 of the trial
3
Evaluate the efficacy of DGPR-1008 (administered 36 hours prior) in conjunction with a near-infrared fluorescence imaging device for intraoperative detection in patients.
Timeframe: From the screening period to the Day 7 of the trial
. Subjects with a history of allergies (e.g., known allergies to two or more medications), those prone to allergic reactions such as rashes or hives, or those with known allergies to the investigational drug (including its formulation components);
. Subjects with significantly abnormal screening test results deemed clinically significant by the investigator and likely to affect study participation; or those with concomitant conditions posing serious safety risks or impeding study completion (except where the investigator determines the condition is stable and allows enrollment);
. Subjects who participated in another clinical trial involving investigational drugs or devices within the month preceding study drug administration;
. Subjects who have undergone neoadjuvant therapy, radiation therapy, focal ablation therapy, hormone therapy, or androgen deprivation therapy within the past 6 months;
. Subjects deemed by the investigator to have other conditions rendering them unsuitable for participation in this trial.
